Synopsis for the Gulf of America

851 PM EST Thu Nov 12 2026



.SYNOPSIS...A strong cold front extending from the Florida Big

Bend to near Brownsville, Texas will rapidly shift across the 

rest of the basin tonight and exit the area early on Fri. Fresh 

to locally strong northwest to north winds will prevail near 

Tampico and Veracruz through early on Fri. Elsewhere, moderate to 

locally fresh north winds are expected in the wake of the cold 

front. High pressure will build southward into the region this 

weekend, with fresh to strong easterly winds across portions of 

the northern and central Gulf. Another strong cold front is 

expected to push off the Texas coast Mon morning, and quickly move

across the basin through Tue night. Fresh to strong winds will 

follow the front across much of the basin. Winds to near gale- 

force are possible in the far NE Gulf early next week.
